Noun
subgoal (plural subgoals)
A lesser goal that forms part of a greater goal.
In the more general case, where sub-goals share variables, other strategies can be used, such as choosing the subgoal that is most highly instantiated or that is sufficiently instantiated so that only one procedure applies. Source: Internet
It would then decompose that goal into sub-goals and then set out to construct strategies that could accomplish each subgoal. Source: Internet
The second subgoal not abnormal(john) of the first candidate solution fails, because wounded(john) succeeds and therefore abnormal(john) succeeds. Source: Internet
